(Master thesis, 2020)Depressive or anxious symptoms are typically connected to chronic and unpredictable high-stress situations or otherwise adverse experiences. In aquaculture, hierarchical disputes and confrontations between individuals in ... -
Effect of farmland type and vegetation height on habitat use and breeding success of northern lapwings in south-east Norway
(Master thesis, 2020)Habitat use is a key element to understanding how endangered species should be protected from further decline. The northern lapwing (Vanellus vanellus) is a red-listed farmland species threatened by multiple factors such ... -
Owls in boxes : what prey do Ural owls (Strix uralensis) bring to their nestlings, when do they bring prey, and how are they handled
(Master thesis, 2020)Earlier studies have investigated the feeding of owl nestlings through examining remains of animals in nests. In some species, like the Ural owls (Strix uralensis), this may give lacking information since they are known ... -
Paleoclimatic reconstruction from laminated lake sediments, Bødalsvatnet, Nordenskiöld Land, Svalbard
(Master thesis, 2020)One predicted consequence of the current warming in the Arctic is an increase of heavy precipitation events. Svalbard have experienced an increase in total annual precipitation and air temperature have affected Svalbard’s ... -
Trace metal speciation and uptake in Atlantic salmon (Salmo salar) in coastal water
(Master thesis, 2020)Estuarine environments have a high risk of metal pollution due to the influx from rivers. Freshwater from rivers mixed with seawater in coastal areas gives varied and complex water chemistry. In the estuarine environment ... -
